梯度酸溶解试验方法在地聚合物体系中的应用

Gradient acid dissolve tests were used to divide geopolymer and hydration product, the feasibility of gradient acid dissolve test was investigated through dissolution rates of geopolymer/hydration product and XRD, FT-IR analyses. The results show the behaviors of dissolution between geopolymer and hydration product are different, the acid point to divide geopolymer and hydration product is pH=3. The gradient acid dissolve test is a semi-quantitative method to divide geopolymer and hydration product well. It will lay a theoretical and experimental basis for further research on the mechanism of geopolymer.
